vstarmi-TIRE CARRIER.

rfhis invention relates generally to spare tire carriers, and has moreparticular reference to a novel type of combinationy spare tire carrieradaptable to various tires.

The invention has for an object the provision of an improved combinationspare tire carrier which will operate efficiently and which can bemanufactured and sold at a low cost.

For further comprehension of the invention and of the objects andadvantages there? of, reference will be had to the following descriptionandaccompanying drawings and to the appended claimsin which the variousnovel featuresof the invention are more particularly set forth.

Referring to the drawings forming a material part of this disclosure:

Fig. 1 is a front view of a device constructed according to thisinvention, certain parts being broken away to disclose the in# teriorthereof. i

Fig. 2 is a vertical sectional view taken on the line 2 2 of Fi 1.

Fig. 3 is a horizonta sectional view taken on the line 3-3 of Fig. 1. v

Fig. 4 is a horizontal sectional view taken on the line 4-1-4 of Fig.1.j

Fig. 5 is al fragmentary front view of portion of thevdevice broken awayin Fig. 1.

Fig. 6 is a fragmentary front view kof a modification of the invention,certain parte being broken away to disclose the interior.

i The reference numeral 9 is applied to certain dot and dash linesindicating the rim of a tire to which the device may be attached. Therear casing 10 abuts against a front casing 11 and both of the casingsare formed with aligned bosses 12 suitably drilled toac commodate screws13 to hold the casings togetherand provide for attaching to a vehicle.The standard 14 projects upwards from the bottom of casing 10 andsupports a horiaontal .shaft 15 formed with outer flattened surfaces 16on one end of the shaft ywhich projects through the casing 11 and beingrotatably supported in the casing 11. vFixed to shaft 15 is a bevel gear17 meshing with anotliei' bevel gear 18 fixed to a vertical threadedshaft 19 supported at its lower end on the standard 14 and at its upperend in a boss 20 depending from the` top of casing l0. A bridging member21 is threadedly engaged on the shaft 19. The casing lOis 'formed with apair of apertures 22 and arms 23 project through the apertures, thebottom Serial N0. 143,089.

respective apertures Y22 and 23, and at the same time permit a limitedsidewise movement of the arms for suitably positioning and working theclaws 24 on the rim 9. The shaft 15 is'formed with a recess 28engageable by a lock 29 fixed to casing 11.

Asuitable tool, not shown on the drawings, may be engaged on the outerend of shaft l5, to turn the shaft, when the lock 29 is in unlockedcondition. This motion will be communicated by gears 17, 18 to shaft 19and the bridging'member 21 may be raisedv ory lowered' to cause the arms23 to change their position to holdor release the rim 10. y.ln themodification shown in Fig. 6, the

arms 23 are formed with central bores 30 engaged by a tongue 31projecting from the claw members 24 to permit an adjustment of thelength of the arms 23 and claw members 24. The tongue members 31 arenormally urged into the recess by springs 32 acting between the tongues31 and the arms 23. One,

edge of the tongue members are formed with ratchet teeth 33' meshingwith a ratchet wheel 34 pivotally mounted in arm 23 so that a portionprojects from the arm to permit manual turning. The other edge of thetongue members are formed with a plurality of apertures 35 engageablebyone end of a pawl 36 pivotally'mounted in arm 23. The arm 23 is formedwith a pair of projections 37 to which is pivotally attached a camhaving a little operatingY handle 39. ,The cam is engageable with thepawl to lock the pawl in the apertures 35, but the pawl may be swung, asindicated by dotted lines on the drawings, to freethe pawl, so that thepawl may be disengaged from the apertures, and

the ratchet wheel 34 manually turned to project the claw member' 24outwards in relaion to the aim 23.

My device may also be used as a tire shoe remover, by forcing one of thefree ends of the tire rim toward the center by means of the claw members24.
